CROSS-REFERENCE TO RELATED APPLICATION

The application claims priority from U.S. Provisional Patent Application No. 62/983,532, filed on Feb. 28, 2020, the contents of which are incorporated herein by reference.

BACKGROUND OF THE INVENTION

The disclosure relates generally to child-resistant containers. More specifically, the disclosure relates to a method and apparatus for preventing child access to a container, such as a medication container.

A container may be configured for a user to apply pressure, which may include unidirectional or bidirectional (e.g., opposing) pressure, to the top and/or bottom of the device to engage features of the container.

Substances have been stored, distributed, and sold in various types of containers. One type of container is known as a pillbox, often with a flip-top opening for manual breaking of a seal or otherwise clear an opening for pouring and consuming the contents.

In some cases, people do not want containers to be easily opened by children or unauthorized individuals when the containers carry a substance that is harmful, controlled, dangerous, or costly.

Some substances are subject to legal restrictions, such as most notably, mind-altering substances, like marijuana and derivatives. Another type of consumable that is restricted is pharmaceuticals and marijuana-based or hemp-based products. Casual consumption can be dangerous if consumed to excess or without proper administration. A chief concern is limiting access to minors (individuals under the local legal age of majority) to avoid harmful consequences. Also, governments institute laws and regulations mandating child-protective barriers to use to prevent minors from accessing controlled substances, such as cannabis and cannabis products.

The European Union and the United States maintain regulations as to child-resistant packaging for drugs and other substances. The United States Consumer Product Safety Commission (CPSC) regulated child-resistant packaging based on the Poison Prevention Packaging Act (PPPA). The special packaging requirements under the PPPA are directed towards designing packaging to make it significantly difficult for children under five years old to open the packaging or obtain a toxic or harmful amount of the substance therein within a reasonable amount of time. The requirements also maintain that it should not be difficult for ordinary adults to use the packaging properly. The PPPA requirements do not dictate that the packaging should be designed such that 100 percent of children cannot open the packaging or obtain a toxic or hazardous amount within a reasonable time. The U.S. child-resistant packaging performance specifications are found in the regulation cited as 16 C.F.R. § 1700.15. The U.S. Food & Drug Administration guidance on child-resistant packaging is available at https://www.fda.gov/media/70788/download. In the United States, individual states usually have their own child-resistant packaging regulations and guidance.

To prevent minors from accessing and consuming controlled substances and to avoid mistaken consumption by people unfamiliar with consumption of cannabis-based beverages, an apparatus to limit and control opening such containers would be useful.

Several have tried to create child-resistant container lids. U.S. Patent Application Publication No. 2019/0315535 A1 to Nicholas Patrick Karll discloses a locking container and lid assembly incorporating a metal plate inside the outer cap or under the outer cap for interacting between the outer cap and a lower cap that are closed by a lock engagement of the lid. However, this document does not disclose a lid fitted for a top of a container without the costly metal plate for preventing child access to container. This metal plate is costly, heavy, and requires excess labor in manufacture, such that a design like the one described below, which can avoid requiring a metal plate insert and thus, be advantageous.

Thus, it would be advantageous to have a device and a method that prevents minor access for safety and waste control.

As will be seen more fully below, the present invention is substantially different in structure, function, and approach from that of the child-resistant containers previously disclosed.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplated modes of carrying out the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

Although the invention is often referred to herein as an apparatus and method for restricting child access to containers, it is understood that such description is not limiting, such that the technology in this invention may be applied in numerous other products and methods, including but not limited to, beverage containers, non-metallic containers, and similar structures.

The container of the invention cannot be easily opened in a conventional manner by a child, yet is easily opened by an adult, especially senior adults, or disabled adults. Another advantage is protecting the container contents from exposure or leakage.

In at least one embodiment, a container may be made largely or completely out of metal. Exemplary metals may include steel, tin, copper, aluminum, and alloys thereof, separately or in combination, in whole, or in part.

Herein is disclosed a three-piece container lid for containers that children will find difficult to open but adults, especially senior adults, and disabled adults, will be able to open the lid readily and easily.

A container may be configured for a user to apply pressure, which may include unidirectional or bidirectional (e.g., opposing) pressure, to the top and/or bottom of the device to engage features on one or more caps or other components, such as on outer and inner caps or inserts, to lock or otherwise couple for opening and/or closing the container. Once engaged, a user may rotate or twist one or more container components and thereby rotate or twist one or more other container components, and in at least one embodiment, place complimentary angled screw threads on an interior wall of a cap and an exterior wall of a container body into threading communication with each other for opening and/or closing a container or one or more caps relative to a container body. When opposing force or pressure is applied to a container cap and body and features, bumps, or indentations of a cap or insert may be aligned with those of another cap or other component, one or more components may depress, deflect, bend, or move and a user may rotate or twist a container cap and/or body for causing one or more threads to engage and separate the lid from the body or attach it thereto. Without such a force by a user or pressure, an outer container lid may be configured to spin around an inner cap without moving or rotating the inner cap or insert. In at least one embodiment, a container may be at least partially air-tight when closed, which may allow the container to safely, or otherwise satisfactorily, store contents for an extended period of time. In at least one embodiment, gas or other fluid inside a container may be altered or treated to have a less reactive gas inside, which may help prevent decay or otherwise preserve a state of a substance stored within the container.

One or more seals, such as a high barrier sealing or lidding film, may be affixed on the top or on another portion of a container body, such as for maintaining a specific or desired atmosphere even after the lid is removed. This may allow, for example, for the contents of a container to be visually inspected without disturbing the atmosphere within the container. Once the seal is initially removed, the atmosphere of the container may no longer be contained or maintained in the same state, but in at least one embodiment a container according to the disclosure may be structured for at least partially preserving or maintaining such an atmosphere.

In at least one embodiment, a container may be made largely or completely out of metal. Exemplary metals may include steel, tin, copper, aluminum, and alloys thereof, separately or in combination, in whole, or in part.

In at least one embodiment, a container according to the disclosure may be configured for a user to apply pressure, which may include unidirectional or bidirectional (e.g., opposing) pressure, to the top and/or bottom of the device to engage couplers on one or more caps or other components, such as on outer and inner caps, to lock or otherwise couple for opening and/or closing the container. Once engaged, a user may twist one or more container components and thereby twist one or more other container components, and in at least one embodiment, place complimentary angled screw threads on an interior wall of a cap and an exterior wall of a container body into threading communication with each other for opening and/or closing a container or one or more caps relative to a container body. When opposing force or pressure is applied to a container cap and body and couplers or indentations of a plate or cap are aligned with those of another cap, one or more components may depress, bend, or move and a user may twist a container cap and/or body for causing one or more threads to catch and separate the lid from the body or attach it thereto. In the absence of such user force or pressure, an exterior container lid may be configured to spin about an inner cap without moving or rotating it. In at least one embodiment, a container may be at least partially airtight when closed, which may allow the container to safely or otherwise satisfactorily store its contents for an extended period of time.

In at least one embodiment, gas or other fluid inside a container may be altered or treated to have a less reactive gas inside, which may help prevent decay or otherwise preserve a state of a substance stored within the container. One or more seals, such as a high barrier sealing or lidding film, may be affixed on the top or another portion of a container body, such as for maintaining a specific or desired atmosphere even after the lid is removed. This may allow, for example, for the contents of a container to be visually inspected without disturbing the atmosphere within the container. Once the seal is initially removed, the atmosphere of the container may no longer be contained or maintained in the same state, but in at least one embodiment a container according to the disclosure may be adapted for at least partially preserving or maintaining such an atmosphere. In at least one embodiment, a container according to the disclosure may be made largely or completely out of metal. Exemplary metals may include steel, tin, copper, aluminum, and alloys thereof, separately or in combination, in whole, or in part. A container according to the disclosure may, in at least one embodiment, prevent or minimize Bisphenol A (BPA) leaching or chemical leaching into a stored product. A container according to the disclosure may be configured for having track and trace information laser etched or otherwise applied onto or into the container in a manner not easily removed or altered. In at least one embodiment, a container according to the disclosure may be at least substantially completely recyclable.

FIG. 10 is a perspective view of another embodiment of a child resistant container according to the disclosure. FIG. 11 is a bottom perspective view of another embodiment of a cap assembly according to the disclosure. FIGS. 1-11 will be described in conjunction with one another. In at least one embodiment, a child resistant container 100 may include a container body 101, such as a housing or casing, for holding one or more products or substances and an outer cap 102, such as a cover or lid, for removably coupling to body 101 to enclose or cover at least a portion thereof, such as an interior 118 volume or space and/or one or more other components or portions of body 101 (e.g., neck 103 further described below). Outer cap 102 and the container body 101 may meet at a junction 120, such as a joint or intersection, which in at least one embodiment may be, or include, an at least partially seamless edge or other transition. For example, in at least one embodiment, body 101 and outer cap 102 may have the same outside diameter or other dimension, in whole or in part. Outer cap 102 may have a top 122 that is at least partially smooth or otherwise configured according to an implementation of the invention and may be configured to couple with body 101 in one or more of the manners further described below.

In at least one embodiment, container body 101 may have a neck 103, such as an extension or collar, for cooperating with one or more other components of container 100. Neck 103 may, but need not, have a diameter or other dimension less than that of another portion, such as a lower portion, of body 101. Neck 103 may be formed integrally with one or more other portions of body 101 or may be formed separately and otherwise coupled thereto. In at least one embodiment, container 100 may include a lip 124, such as a rim, stop, or collar, that extends radially inwardly from an exterior surface 126 of body 101. In such an embodiment outer cap 102 or one or more components coupled thereto may contact or rest on or against lip 124 (e.g., when outer cap 102 is in one or more closed positions), separately or in combination, in whole or in part. As other examples, outer cap 102 or one or more components coupled thereto may be disposed adjacent to, above, or otherwise relative to lip 124 when outer cap 102 is in one or more closed positions. In at least one embodiment, container body 101 or a portion thereof, such as a top portion or neck 103 (if present), may include an inwardly rolled edge 107 for cooperating with one or more other components of container 100 as described in further detail below. Edge 107 may be rolled or otherwise disposed radially inwardly (e.g., about central longitudinal axis X) from an exterior surface of body 101 or neck 103, in whole or in part, and may extend or otherwise exist about all or a portion of the mouth 128 or opening of body 101. Edge 107 may include a partial roll or a full roll and may be continuous or comprise one or more segments about mouth 128, separately or in combination, in whole or in part.

Container 100 may include an inner cap 105, such as a cover or lid, for removably coupling to body 101 to enclose or cover at least a portion thereof, such as an interior 118 volume or space and/or one or more other components or portions of body 101 (e.g., neck 103 or edge 107). Inner cap 105 may be coupled to outer cap 102, which may include being disposed at least partially therein, and configured to couple outer cap 102 and/or one or more other components of container 100 to container body 101. In at least one embodiment, inner cap 105 may have one or more dimensions (e.g., height and diameter or other radial dimension) smaller than one or more corresponding dimensions of outer cap 102 and inner cap 105 may be retained or otherwise disposed within outer cap 102 (see, e.g., FIGS. 3B-3C). For example, outer cap 102 may include an inwardly rolled or otherwise protruding edge 130 extending radially inwardly to form an inside dimension greater than an outside dimension of inner cap 105 and which may at least partially resist or prevent removal of inner cap 105 therefrom. In at least one embodiment, inner cap 105 may have an outwardly rolled or otherwise protruding edge 132 for cooperating with inwardly rolled edge 130 of outer cap 102 in one or more ways. For example, outwardly rolled edge 132 and inwardly rolled edge 130 may cooperate to retain at least a portion of inner cap 105 within at least a portion of outer cap 102. In at least one embodiment, at least a portion of inner cap 105 may “float” within at least a portion of outer cap 102 such that caps 102, 105 may move somewhat relative to one another in one or more directions. In at least one embodiment, one or more holes 146, such as an opening or other space (which may include a space created by, e.g., a contour or indentation), may be disposed in one or more locations on an interior surface or other portion of any of caps 102, 105 (and/or plates 110, further described below) for allowing lateral or other movement of one or more components relative to one or more other components of container 100. For example, as illustrated in FIGS. 3D-3E, a center or locking cap (or middle lid) 110 may include one or more holes 146 therein or therethrough for allowing outer cap 102 and/or cap 110 and inner cap 105 to move in one or more lateral directions relative at least partially to one another, which may, for example, at least partially minimize a possibility of cross-threading or other binding of threads during installation or removal of cap assembly 114 to or from container body 101. As another example, outwardly rolled edge 132 and inwardly rolled edge 130 may be adapted for sliding engagement with one another when caps 102, 105 are in one or more positions relative to one another (further described below), such as for supporting rotation of one of caps 102, 105 relative to the other. One or both of edges 130, 132 may be rolled or otherwise disposed radially inwardly or outwardly (e.g., about central longitudinal axis X) from a surface of their respective caps, in whole or in part, and may extend or otherwise exist about all or a portion of such caps. One or both of edges 130, 132 may include a partial roll or a full roll and may be continuous or comprise one or more segments about their respective caps, separately or in combination, in whole or in part. As another example, at least a portion of one or more of edges 130, 132 may be formed by crimping, pressing, bending, or folding a portion of cap material to form such edge(s) or rim(s) (see, e.g., FIGS. 3B-3C), separately or in combination with one another and/or with rolling of the material, in whole or in part.

Inner cap 105 and outer cap 102, together with one or more other cap components, such as cap 110, if present, may be configured for optionally coupling with one another in one or more positions to optionally translate opening and/or closing force from one to the other. Inner cap 105 and outer cap 102 may collectively form or be part of a cap assembly 114. More specifically, inner cap 105 and outer cap 102 may have one or more positions relative to one another (e.g., in an axial direction along axis X) and may cooperate with one another and/or one or more other components of container 100 to form a child resistant opening/closing mechanism or otherwise accomplish child resistant functionality. In this regard, each of outer cap 102 and inner cap 105 may include one or more couplers 134, 136 for optionally coupling with one another to engage outer cap 102 and inner cap 105 for at least partially simultaneous rotation (e.g., about axis X) relative to one or more other components of container 100, such as container body 101. In at least one embodiment, couplers 134, 136 may be, or include, one or more mating indentations, depressions, or other formations as further described below. In at least one embodiment, one or more of caps 102, 105 may include gripping material (not shown), such as silicone, rubber, or another elastomeric or sticky material, coupled thereto for increasing friction between or otherwise supporting rotational engagement of caps 102, 105 in one or more positions. For example, gripping material may be included on one or more of the undersides of outer cap 102 (or, e.g., cap 110 further described below) and the top side of cap 105, separately or in combination with the presence of one or more other couplers 134, 136 and, in at least one embodiment, may be included on one or more couplers 134, 136.

For example, as seen in FIGS. 3B-3C, in at least one embodiment, outer cap 102 may have one or more couplers 134 and inner cap 105 may have one or more couplers 136 and outer and inner caps 102, 105 may have one or more optional positions relative to one another for engagement and/or disengagement of one or more couplers 134, 136. As shown in FIG. 3B, for instance, outer and inner caps 102, 105 may have one or more uncoupled positions wherein couplers 134, 136 are uncoupled and axially separated from one another by a distance d along axis X, which may be any distance according to an implementation of the disclosure. In such a position (or another uncoupled position), outer and inner caps 102, 105 may relatively freely rotate relative to one another (i.e., subject to outside forces such as friction or gravity) and, for example, outer cap 102 may be rotated about inner cap 105 without causing rotation of inner cap 105. As shown in FIG. 3C, for instance, outer and inner caps 102, 105 may have one or more coupled positions wherein couplers 134, 136 are coupled and in which the axial separation is less than that of an uncoupled position (in whole or in part, and which may include zero). In such a position (or another coupled position), outer and inner caps 102, 105 may be at least partially rotationally fixed relative to one another so as to rotate together about, e.g., container body 101. One or more couplers 134 may engage one or more couplers 136 and, for example, may translate rotational force or motion from outer cap 102 to inner cap 105 or vice versa such that rotation of one causes at least some rotation of the other. In at least one embodiment, one or more axial forces or pressures and/or one or more rotational forces (as schematically illustrated by the various arrows in FIG. 3C) may be applied to one or more of outer cap 102 and inner cap 105, or one or more components coupled thereto (e.g., container body 101), to moves caps 102, 105 from an uncoupled position to a coupled position, which may, but need not, include elastic (or plastic) deformation of at least a portion of one or more of caps 102, 105. During a transition from an uncoupled position to a coupled position, outer cap 102 may, but need not, at least partially rotate relative to inner cap 105, e.g., depending on the relative positions or alignment of caps 102, 105 and/or couplers 134, 136 upon the transition. In at least one embodiment, one or more of caps 102, 105 may be adapted for biasing caps 102, 105 and/or couplers 134, 136 toward an uncoupled position, such as by way of being shaped or otherwise configured for functioning similarly to a spring such that one or more of caps 102, 105 and/or couplers 134, 136 is forced or otherwise biased away from the other in a default position. The respective rolled edges 130, 132 of caps 102, 105 may, but need not, be in contact with one another in one or more coupled positions or uncoupled positions. For example, while rolled edges 130, 132 are shown to be axially separated in the embodiment of FIG. 3C for illustrative purposes, this need not be the case and alternatively, or collectively, rolled edges 130, 132 may be in contact with one another in one or more coupled positions of caps 102, 105 and/or couplers 134, 136 and, e.g., the top of outer cap 102 may be configured to elastically deform or otherwise move sufficiently during actuation to couple one or more couplers 134, 136 rolled edges 130, 132 are in contact with one another, whether in whole or in part.

As shown in an exemplary embodiment of FIGS. 1-3A, container 100 may include one or more threads 104 for coupling engagement with one or more mating threads 138 of inner cap 105 for coupling and uncoupling outer cap 102, inner cap 105 (and/or one or more other container components), and container body 101. In at least one embodiment, container 100 may include one or more threads 104, 138 adapted for opening or closing container 100, or coupling or uncoupling one or more caps (e.g., 102, 105) with, or from, body 101, in one-quarter turn (see, e.g., FIGS. 10-11), one-half turn, three-quarters turn, one full turn, two full turns, or less or more. In at least one embodiment, container 100 and thread(s) 104, 138 may be adapted for coupling and/or uncoupling outer cap 102 and container body 101 in no greater than two full turns, which may at least partially minimize or prevent slipping or cross-threading when a user applies pressure to the outer cap 102 and container body 101. Threads 104, 138 may be configured accordingly and, in at least one embodiment, may include stops or lands 148 formed therein or otherwise on container 100 to stop closing rotation of cap assembly 114 or a component thereof, such as upon reaching a fully closed position, and/or for at least partially resisting opening rotation, such as to guard against accidental or unintended opening of container 100. To this end, in at least one embodiment, threads 104, 138 may be limited to a single thread or, for instance, a set of threads configured to accomplish full closure of container 100 in less than or equal to one turn or two turns or so (e.g., of inner cap 105 and/or outer cap 102 relative to container body 101 or neck 103).

Couplers 134, 136 may take various forms, separately or in combination, in whole or in part. In at least one embodiment, one or more couplers 134, 136 may be, or include, one or more indentations stamped, molded, debossed, or otherwise formed in or on outer cap 102 or inner cap 105, such as, for example, into one or more sheets or other piece(s) of material from which all or a portion of outer cap 102 or inner cap 105 may be made. Accordingly, couplers 134, 136 may be referred to herein as indentations (and collectively as indentations 106) for purposes of convenience of illustration, but it will nonetheless be understood that such references may apply to couplers 134, 136 of numerous other types or forms, such as couplers machined into material or couplers formed separately and coupled to one or more other pieces of material mechanically or otherwise.

Each of outer cap 102 and inner cap 105 may have one or more indentations 106 on one or more of its surfaces, such as in a top surface and/or protruding or otherwise extending downwardly from a bottom or interior surface. One or more of the indentations 106 may match one or more indentations 106 present on the other cap and may be disposed at a point or points where force(s) or pressure from a user is converted into friction or other actuation force(s) for allowing container 100 to be opened or closed. The number, shape, size, location, and pattern of one or more indentations 106 may vary from embodiment to embodiment. The embodiment depicted in FIGS. 1-3, shows a cross-like formation comprising four generally rectangularly shaped indentations 106 that extend radially outwardly from axis X, but which do not intersect. As another example, FIG. 5A shows a similar cross-like pattern comprising a single or continuous indentation 106 that includes four (or two) intersecting rectangular or prism sections forming a cross-type shape. However, these are but two of many examples presented for purposes of illustration and explanation and are by no means limiting as to the numerous potential embodiments of the present disclosure. Outer cap 102 and/or inner cap 105 may include any number and configuration of indentations 106 that accomplish the functions of embodiments of the disclosure, and may include one or more indentations 106 comprising at least one working surface in each of the clockwise (CW) and counterclockwise (CCW) (also known as anticlockwise) directions for providing a coupler edge or side that may cooperate with one another during opening and closing coupling engagement of caps 102, 105 (which may occur in the CCW and CW directions, respectively, or vice versa). For instance, in at least one embodiment, one or more of outer cap 102 and inner cap 105 may include four rectangular or otherwise shaped indentations 106, a single cross or similarly shaped indentation 111, a single linear indentation, one or more curved indentations, or multiple indentations, of, e.g., two, three, four, five, six, seven, eight, or more equally, or unequally spaced indentations. Outer cap 102 and inner cap 105 may have the same number of indentations 106 or a different number of indentations 106. Further, the size and/or shape of one or more indentations 106 of inner cap 105 may be the same as or different from the size and/or shape of one or more indentations 106 of outer cap 102, separately or in combination, in whole or in part. For example, in at least one embodiment, inner cap 105 may have a greater number of indentations 106 than outer cap 102, or vice versa. As another example, each of one or more indentations 106 on one of caps 102, 105 may be configured to couple with one, some, or all of one or more indentations 106 on the other of caps 102, 105. For instance, in at least one embodiment, outer cap 102 may have an indentation 106 configured to couple with any of two or more indentations 106 of inner cap 105 and such indentations may be of the same or different shapes and/or sizes. Alternatively, or collectively, outer cap 102 may have an indentation 106 configured to couple with only a particular one(s) of one or more indentations 106 of inner cap 105, which indentations may, once again, be of the same or different shapes and/or sizes. In at least some implementations of the disclosure, a relatively greater number of indentations 106 may be used for larger containers and fewer indentations 106 may be used for smaller containers. However, this need not be the case and the number of indentations used for a particular implementation of the disclosure may depend on one or more factors such as container size, shape, material, cost, aesthetics, contents, functionality, and quality requirements, among other things, such as indentation size and shape. In at least one embodiment, a container having a diameter less than or equal to 70 mm may have four or fewer indentations 106 and may be made from material having a thickness of between 4.5 mm and 6 mm or so, which may at least partially minimize or prevent ripping or tearing of the material during manufacturing.

With continuing reference to the figures and particular reference to FIG. 4, one or more exemplary working surfaces of an indentation 106 is shown and described in more detail. One or more indentations 106 on outer cap 102 and/or inner cap 105 may include one or more open edges 108 for opening container 100 and one or more working edges 109 for closing container 100. One or more open edges 108 on outer cap 102 may engage one or more open edges 108 on inner cap 105, such as when caps 102, 105 are in a coupled position, for opening container 100. One or more working edges 109 on outer cap 102 may engage one or more working edges 109 on inner cap 105, such as when caps 102, 105 are in a coupled position, for closing container 100. Open edge 108 may be disposed at an angle A relative to horizontal and working edge 109 may be disposed at an angle B relative to horizontal. Angles A and B may be the same or different, whether for a given indentation 106 or two or more different indentations 106. In at least one embodiment, two or more different angles may be used on one or more edges. In at least one embodiment, angle B may be adapted to at least partially minimize or prevent overtightening, which may potentially make container 100 difficult to open. For example, angle B may be steep enough for transmitting closing force from outer cap 102 to inner cap 105 but shallow enough for facilitating at least partial disengagement or skipping of caps 102, 105 or two or more indentations 106 relative to one another upon reaching a fully closed position of inner cap 105, which may be, or include, any position about container body 101 according to an implementation of the disclosure. In at least one embodiment, angle A of open edge 108 may be steeper than angle B of working wedge 109, but that need not be the case. In at least one embodiment, one or more indentations 106 may have a working edge angle B of 75 degrees or in the range of 70 to 80 degrees or about 70 to 80 degrees. The angle may allow the mechanism to disengage when sealed tight, but that need not be the case. In at least one embodiment, one or more indentations 106 may have an open edge angle A of 60 degrees or in the range of 40 to 60 degrees or about 40 to 60 degrees. In at least one embodiment, such an angle A may decrease or minimize the amount of twist force to be exerted compensating for the closing motion while still requiring a push-down-and-twist motion to open the container. The range of 40 to 60 degrees from the horizontal may be used for the open edge. In at least one embodiment, such an angle A may cause container 100 to operate with enough difficulty to achieve child resistant requirements but not so difficult that adults are unable to reliably open the device. In at least one embodiment, one or more indentations 106 may have a working edge angle B of 60 degrees or in the range of 50 to 70 degrees or about 50 to 70 degrees. The angle may allow the mechanism to disengage when closed, but that need not be the case. In at least one embodiment, one or more indentations 106 may have an open edge angle A of 65 degrees or in the range of 55 to 75 degrees or about 55 to 75 degrees. In at least one embodiment, such an angle A may decrease or minimize the amount of twist force to be exerted compensating for the closing motion while still requiring a push-down-and-twist motion to open the container. In at least one embodiment, such as one or more of those mentioned above, working angle B may be adapted to allow for skipping of outer cap 102 relative to inner lid 105 upon reaching a closed position, which may mechanically and/or audibly signal a user that container 100 is in a fully closed or other state.

With continuing reference to the figures and particular reference to FIGS. 5A-6 (see also FIGS. 3B-3C), one or more exemplary embodiments of a container 100 having a center cap 110 is shown and described in more detail. As discussed above with reference to, e.g., FIGS. 1-3A, container 100 may include inner and outer caps (or lids) 105, 102 each having one or more couplers or indentations 106 thereon for cooperating with one another in one or more manners according to the disclosure. However, in at least one embodiment, it may be desired to form one or more indentations 106 of outer cap 102 by stamping or pressing or another integral manner while nonetheless maintaining the top 122 or outer surface of outer cap 102 in a smooth or other condition that differs from or does not include such indentation(s) 106 (see, e.g., FIG. 1), whether for aesthetic purposes or otherwise. In such an embodiment, or in other embodiments, container 100 may include one or more caps 110, such as a disk, having such indentation(s) 106 and coupled to outer cap 102 and disposed at least partially between outer cap 102 and inner cap 105. Cap 110 may be flat, curved, cylindrical, annular, or otherwise shaped for functioning according to the disclosure, separately or in combination, in whole or in part. Cap 110 may be rotationally fixed relative to outer cap 102 so as to function in at least substantially the same way as described elsewhere herein with regard to an embodiment of outer cap 102 having one or more indentations 106 formed directly thereon or otherwise coupled directly thereto. In at least one embodiment, Cap 110 may be, or include, a third cap, disposed at least partially between outer cap 102 and inner cap 105 (see, e.g., FIGS. 3B-3C). Cap 110 may be coupled to inner cap 105 and/or outer cap 102 in any manner according to an implementation of the disclosure, which may, but need not, include having a rim or other portion rolled, crimped, or otherwise formed simultaneously with one or more of rolled edges 130, 132 on caps 102, 105 (see, e.g., FIGS. 3B-3C). In at least one embodiment, one or more center caps 110 may be attached to the inside of outer cap 102 and/or placed between caps 102, 105 and may be configured such that a user must press or otherwise bias container body 101 and/or outer cap 102/center cap 110 together or toward one another while or prior to applying horizontal rotational force for coupling and/or uncoupling the caps from body 101 to close or open container 100.

FIG. 5A depicts one embodiment of a center cap 110, which may be located at least partially between inner cap 105 and outer cap 102. Center cap 110 may be attached to inner cap 105 and/or outer cap 102 in any manner according to an implementation of the disclosure, including, but not limited to, mechanically, using one or more fasteners and/or by way of adhesive or other bonding measure(s). In at least one embodiment, center cap 110 may be disposed in between outer cap 102 and inner cap 105 without adhesive or another bonding agent and may be at least rotationally fixed relative to outer cap 102 mechanically, such as by way of rolling, stamping, bending, or otherwise manipulating at least a portion of each of cap 110 and outer cap 102 to connect the two components to one another and/or resist independent rotation. For example, in at least one embodiment, an outer cap 102 and cap 110 may include an at least partially collectively rolled or otherwise formed edge 144 (see, e.g., FIGS. 3B-3C), which may, but need not, include one or more crimps, dents, notches, or other couplers (e.g., in a radially inward or outward direction) for further supporting rotational fixation between outer cap 102 and cap 110. Center cap 110 may have one or more indentations 111 that at least partially match and fit into one or more indentations 106 on inner cap 105. When pressed together by a user, the indentations 111, 106 of center cap 110 and inner cap 105 may couple with one another and allow the locking center cap 110, inner cap 105, and outer cap 102 to be unscrewed and/or separated from container body 101 or, conversely, screwed onto container body 101. The indentations 111 illustrated in FIGS. 5A-6 are but some embodiments of many according to the disclosure. Indentations 111 may include one or more working edges 112 and open edges 113 on opposite sides of one or more indentations 111 or one or more portions thereof that may couple with indentations 106 on inner cap 105 for closing and opening the lid assembly accordingly. In at least one embodiment, one or more center locking caps 110 may be used, for example, where indentations 106, 111 are not manufactured into or directly coupled to outer cap 102. In at least one embodiment, an outer cap 102 with a smooth or otherwise configured top surface 122 may be desired and center cap 110 having one or more indentations 111 may be affixed to the inside of outer cap 102 in lieu of (or collectively with) one or more indentations on outer cap 102. Outer cap 102 may be used to press cap 100 downwardly or otherwise toward inner cap 105 to engage one or more indentations 106, 111 and allow inner cap 105 and outer cap 102 (and center cap 110) to turn as one. As illustrated in FIGS. 5A-6 for exemplary purposes, one or more indentations 111 may, but need not, extend to or otherwise be disposed at the center of cap 110 and/or all the way to the radial exterior or termination of cap 110.

As shown in FIG. 6, outer cap 102 may be disposed at least partially over inner cap 105 and locking center cap 110 and may be configured to couple with container body 101, such as by coupling with neck 103 and/or lip 124, which may but need not include forming a seamless edge 120. Outer cap 102 may have an inwardly rolled or otherwise formed edge 130 on its open end and may include a channel 140 for holding at least a portion of inner cap 105 and/or center cap 110 (if present). Inner cap 105 may fit in the channel and at least a portion may be retained such that it cannot exit channel 140 but nonetheless may at least partially float and rotate inside channel 140. In at least one embodiment, the fit of outer cap 102 on inner cap 105 may be loose enough that turning outer cap 102 will not turn inner cap 105 against the resistance of container body 101 or threads 104. When outer cap 102 is pushed down by a user, it and/or locking center cap 110 (if present) may lock with inner cap 105 via indentations 106, 111 for separating the entire cap assembly or unit from container body 101 and/or coupling it thereto.

In at least one embodiment, outer cap 102 may be stamped or otherwise outfitted with one or more indentations 106, 111 instead of (or alongside) using one or more center caps 110. In such an embodiment, one or more indentations 106, 111 may be manufactured into outer cap 102 and may interact directly (or indirectly) with one or more indentations on inner cap 105 (and/or center cap 110, if present). The same open and working angles may, but need not, be used in the case where outer cap 102 does not have indentations therein or thereon. In at least one embodiment, such as an embodiment wherein outer cap 102 does not require a smooth superior exterior surface plane, center cap 110 may be absent and one or more indentations 106, 111 may be embossed or otherwise manufactured into the superior exterior surface plane of outer cap 102 for matching or coupling with one or more indentations 106, 111 of inner cap 105. Accordingly, embodiments of the disclosure may have lid or cap assemblies (or units) comprising a number of cap components coupled to one another, such as a two-piece lid or a three-piece lid (e.g., with a locking center cap included); however, embodiments having more or fewer components are also possible.

In at least one embodiment, container 100 may include one or more seals 115, such as a lidding film, sealing film, or other closure for creating an at least partially airtight seal, whether initially, repeatedly, or otherwise (see, e.g., FIG. 7). One or more seals 115 may be coupled to any of container body 101, outer cap (or lid) 102, inner cap (or lid) 105 and center cap 110, separately or in combination, in whole or in part. In at least one embodiment, seal 115 may be used over the opening of container body 101 and may, for example, be applied during packaging of a product. In at least one embodiment, seal 115 may at least partially prevent the escape of an inert gas or other fluid within container 100, such as, for example, a gas or other fluid for supporting prolonged, safe, fresh, or otherwise desirable storage of one or more products stored in container 100. In at least one embodiment, one or more seals 115 may be coupled to inwardly rolled edge 107 on neck 103 and/or another portion of neck 103, such as on its radial exterior surface. In at least one embodiment, edge 107 may form or include a coupling surface sufficient to support coupling of seal 115 to container body 101, temporarily, permanently, or otherwise. For example, in at least one embodiment, edge 107 may be, or include, one or more flat or curved surfaces at least 2 mm thick (e.g., in the radial direction about axis X) for a lidding film or induction film to bond; however, numerous other configurations are possible.

In at least one embodiment, seal 115 may be, or include, a multi-layered seal, such as a multi-layer aluminum foil seal or other type of seal having a plurality of layers (which may be of the same or different material(s)). Seal 115 may be disposed at least partially over the opening of container body 101 and may be attached to inwardly rolled edge 107. In at least one embodiment, seal 115 may be, or include, one or more annular silicone or otherwise elastomeric seals, such as a gasket, coupled to one or more of caps 102, 105 (or center cap 110, if present). Seal 115 may be sealed or otherwise coupled to container body 101 in any manner according to an implementation of the disclosure, such as by way of a heat-activated adhesive coating, induction sealing, conduction sealing, or otherwise. In at least one embodiment, seal 115 may be, or include, one or more desiccant materials and/or oxygen scavenging materials 116. For instance, one or more materials 116 may be applied or otherwise coupled to one or more sides of seal 115, such as a product facing side 142 of seal 115 disposed at least partially within or toward the bottom interior of container body 101 or a product disposed within container body 101 (e.g., when seal 115 is at least partially coupled to edge 107). In at least one embodiment, seal 115 may be, or include, a tamper-evident seal, which may be used alone or, for example, in addition to one or more tamper-evident seals or packaging on the outside of container 100. In at least one embodiment, seal 115 may be configured to provide an at least partial barrier to light, oxygen, air, water, odors, and/or one or more other environmental or other conditions in an atmosphere surrounding container 100. In at least one embodiment, seal 115 may be contact-conduction sealed to inward rolled edge 107 of container body 101 of a metal child-resistant container 100. One or more seals 115 may be either flat or recessed, separately or in combination, in whole or in part. In at least one embodiment, one or more seals 115 may have at least one of a protective lacquer layer, an aluminum foil layer, an extrusion coating layer (e.g., with a heat-activated adhesive), and a combination thereof.

In at least one embodiment, desiccant material and/or oxygen scavenging material 116 may be, or include, at least one of activated alumina, aerogel, benzophenone, bentonite clay, calcium chloride, calcium oxide, calcium sulfate (gypsum), cobalt(II) chloride, copper(II) sulfate, lithium chloride, lithium bromide, magnesium sulfate, magnesium perchlorate, molecular sieve, potassium carbonate, potassium hydroxide, silica gel, sodium, sodium chlorate, sodium chloride, sodium hydroxide, sodium sulfate, sucrose, or sulfuric acid, ferrous carbonate, metal halide catalyst, ascorbate, sodium hydrogen carbonate, citrus, ascorbic acid, and a combination thereof. The amount and material makeup of desiccant material and/or oxygen scavenging material 116 may vary from embodiment to embodiment. In at least one embodiment, material 116 may be configured to maintain a relative humidity (RH) inside container 100 of between 50-65% or so. In at least one embodiment, desiccant material and/or oxygen scavenging material 116 may be applied to a portion of seal 115 or otherwise configured for allowing a heat-activated adhesive layer of seal 115 to still function properly, which may, for example, at least partially reduce as need for nitrogen flushing or separate desiccant packets in one possible implementation of the disclosure. In at least one embodiment, desiccant material and/or oxygen scavenging material 116 may be coupled to one or more seals 115 by heat staking and/or adhesive, whether separately or in combination with one or more other couplers or coupling manners.

FIGS. 8A, 8B, and 8C depict some embodiments of a seal 115 having desiccant material and/or oxygen scavenging material 116 according to the disclosure for illustrative purposes. For example, in at least one embodiment, one or more seals 115 may be, or include, one or more desiccant material and/or oxygen scavenging materials 116 in the form of one or more strips, stickers, patches, or other media, which may be of any size and/or shape according to an implementation of the disclosure, such as circular, annular, square, rectangular, or otherwise. Desiccant material and/or oxygen scavenging material 116 may be made as large or small as necessary (e.g., by weight, volume, area, or another measure) to create a desired RH or other atmosphere inside an embodiment of container 100, which may be, or include, any atmosphere according to an implementation of the disclosure. One or more strips, patches, or other holders of desiccant material and/or oxygen scavenging material 116 may be attached to the inside or product facing side 142 of seal 115 (and/or elsewhere, such as anywhere inside container 100). Strips, patches, or other holders of desiccant material and/or oxygen scavenging material 116 may be modular so as to allow for different amounts of desiccant material and/or oxygen scavenging material 116 to be used among one or more embodiments for creating a desired atmosphere inside container 100 by adding and/or subtracting incremental units of desiccant material and/or oxygen scavenging material 116.

FIGS. 9A and 9B depict one embodiment of a container 100 according to the disclosure having a port 117. In at least one embodiment, container 100 may include one or more ports 117, such as a closed or optionally openable space or portal, for enabling a user to view the contents of container 100 while at least having the option of doing so without at least partially removing seal 115 from container 100. In at least one embodiment, port 117 may be, or include, one or more holes or other openings in or through seal 115 and covered by an at least partially clear or translucent film. A port may allow a product stored and sealed in container 100 to be viewed without a seal 115 being broken, which may include allowing a customer or other user to view a product and know the seal and/or product have not been tampered with.
